City forester: Diversity, upkeep key to keeping trees healthy

ROCKFORD — Rockford may be known as the Forest City, but without vigilance and care that signifier could one day be in danger.

ROCKFORD — Rockford may be known as the Forest City, but without vigilance and care that signifier could one day be in danger.

That was the message at an annual Rockford Public Works Forestry Division tree planting and Arbor Day celebration Friday at a Newburg Road well station. The ceremony was highlighted by the planting of a new black tupelo, a species of tree native to southern Illinois that also thrives in the northern part of the state.

“Its leaves have such bright, beautiful fall colors,” said City Forester Brandon Larson, who addressed attendees before the tree was planted. “But maintenance and support is key, for this and all trees in the area.”

Rockford’s tree population has come under duress in recent years because of a high number of invasive insects and diseases. The city intends to plant more than 1,000 trees this year as part of its reforestation efforts, said city Street Supervisor Mark Stockman.

“We’re looking to have a one-to-one ratio of planting to deforestation with 80 percent of these new trees being placed in neighborhoods,” he said.

Trees are vital to the quality of life within a community, providing aesthetic value, mitigating storm water runoff and reducing utility costs, and for homeowners, knowing the warning signs of trees in trouble can be make or break.

These signs range from an extreme die-back of leaves to an increase in the number of woodpeckers that attempt to dig out harmful insects for food. Residents and property owners can follow these tips, Larson said, to ensure tree health and safety:

Diversity: Planting more than one species of tree on your property can prevent insects and diseases from wiping out all of your trees.

Mulching: While mulching is beneficial to new plantings, it’s helpful to spread mulch in a dish shape as opposed to a dome to allow water to absorb more effectively into a tree’s root system.

Watering: New trees require one gallon of water per week, or one inch of rainfall and the amount of water needed is something homeowners often underestimate.

Trimming: Pruning trees every seven to 10 years fosters healthy growth and reduces the risk of damage to homes and pedestrians from falling branches.

Research: Do your homework. Being knowledgeable about the species and its vulnerabilities can be the most crucial aspect in cultivating new trees, and if you suspect a tree is in danger, consulting a certified arborist is the best way to go.
